We usually use knives, graters, scissors, pencil sharpeners, a saw, and so on in our daily life for cutting. Do you know how these products are manufactured? They also are made of cutting tools. These cutting tools share a common property which is that they all change the shapes of things by cutting and producing chips. As we know, cutting tools are tools that cutting things to acquire the desired shape, cutting tools in our daily life cut fruits, vegetables, and wood. But the cutting tools produced by Zhuzhou Xinhua cemented carbide industrial co.Ltd cut harder materials such as steel, stainless steel, cast iron. MANUFACTURING PROCESS OF CARBIDE TOOLS Let’s see the manufacturing process of carbide. First, mix tungsten carbide with cobalt to make powder which can be classified as raw materials. The granulated mixture is poured into a die cavity and pressed. It gives a moderate strength like that of chalk. Next, the pressed compacts are placed in a sintering furnace and heated at a temperature of about 1400°Resulting in cemented carbide. After sintering, the content volume shrinks considerably. Also, the hardness of cemented carbide is at a level between diamond and sapphire and its weight is about twice as iron. Then, how do we cut this hard cemented carbide? What is Cutting?
